If technology allowed humanity to live forever in the future, would you take the ticket? We asked our readers recently and were surprised to see the balance tilt towards “No” (60% of respondents). One answer was hidden in a comment from one of our readers – they would want to live forever, yet only if they stayed young. Among others, living long worries people as it is associated with getting old and suffering from various diseases. 

Yet if technology allows us to extend our life spans it will also likely improve our health spans. According to demographers, children today have a better chance of living up to 100 years old than ever before. But their lives won’t be just longer, they will also benefit from day-to-day technological advances aimed at improving their well-being, preventing diseases, and keeping their minds and bodies in shape.

Slowing aging presents an economic opportunity, too. In the US, an estimate shows that just one to two years increase in life expectancy are worth between $7 trillion and $38 trillion. The nascent longevity and anti-aging industry is set to reach $64 billion by 2026 from $44 billion in 2020. 

Startups are at the forefront of the search for immortality, with a wide range of solutions to hack aging mechanisms in humans and their pets, from cellular rejuvenation programming and gene therapy, to anti-aging drugs (also known as regenerative medicine), biomarkers, or cryopreservation.

Read on for an overview of some of the most noteworthy and promising longevity startups in Europe. If you see a company missing, message us at [email protected]
